Is black hole a 3D object like a sun? If so, I assume the light in the event horizon cover the whole object, i mean 3D shaped as well. How the picture taken from the telescope shown the dark area where the black hole is located? I mean, shouldn’t the whole black hole covered by the light thus we can’t see the black hole?

It's actually in a galaxy called Messier 87 which is 55 million lightyears away.
Oh, interesting! Wouldn't it be easier to photograph our own? :-)

Excellent example of successful international collaboration, with distributed team. Great results and promising future work: they say Sagitarius-A* is their next target!

Nope, for the same reason we had photos of the Moon before we had photos of Earth.
Can you expand on this?
It doesn't sound like they just snapped a picture. The one guy says they used "supercomputers" for 6 months to get the image. Sunspots look black relative to the rest of the sun but are actually very bright. Could this be the same thing? How did they set the black level? Is there a description of the procedure somewhere? EDIT: Found the paper describing the data processing: https://iopscience.iop.org/article/10.3847/…
Indeed, from what I gather from this thread and external links this “image” seems to be more of a plot than an image. In fact, are we looking at a matplotlib plot of the data with a “hot” colormap? The iopscience paper even references matplotlib. I’m just making some educated guesses here, but it’s still fun to think about. BTW: Python for the win! iopscience paper makes several references to Python tools (e.g., nump…

What? You obviously didn't read what I wrote.
> "What? You obviously didn't read what I wrote. Are you ok?" You're ranting about Saturn and Jupiter for some reason. Why don't you calm down and look at page eight of the paper that Veritasium video was based on: https://ve42.co/luminet "Image of a spherical black hole with thin accretion disk Astronomy and Astrophysics, vol. 75, no. 1-2, May 1979, p. 228-235" Look at that last image, and squint at it until it gets…
